RECLINING-CHAIR.

SPECIFICATION forming part of Letters Patent No. 376,105, dated January10, 1888.

Application filed June 3, 1886. Serial No. 204,082. (No model.)

ings, forming part of this specification.

My invention has reference to recliningchairs in which the position canbe readily changed from a sitting to any reclining position desired, andvice versa, by the person sitting on the chair or by an attendant.

In the drawings, Figure 1 is a perspective view of the chair inverted toshow the working parts. Fig. 2 is a vertical section, the motion of thechair being indicated in dotted lines. Fig. 3 is a plan view of theworking parts of the chair invert-ed. Fig. 4 is a section of the arm andback at the pin d.

In the drawings, A A are the two sides of a chair-frame, which arefirmly fastened to the frame B.

G is the back of the chair hinged to sliding seat D ate 1), and pivotedto each side of the chair at 0 d with a'pin provided with a shoulderturning in a metal slide set therein.

E is a coiled spring attached to frame B at e and sliding seat D atf,which expands more or less as the back is reclined, making the chairautomatic and easily adjusted.

To the chair-frame B is attached, atg h and j k, strips F G, havingbeveled faces Zm, and

to the seat D, at n 0, is fastened strip H, having beveled faces 12 1,arranged so that the facesl m andp 7 meet, which serves to hold the seatD to the frame or bed of the chair while it slides laterally therein.

On the under side of strip H is fastened the saw-toothed casting I,which, with the counterpart casting J on the upper side of strip K,serves to hold the seat at any point desired whenever the teeth areinterlocked. Strip K is hinged to the front stretcher at s, or it may behinged to rear stretcher of the chair. This arrangement admits of thestrip K dropping so as to unlock the chair. By using saw-toothedcastings the occupant can invariably lock the chair without hinderance.arising from the end of the teeth striking upon each other, which wouldbe the case if ordinary cogs were used; for in any event, when throwntogether, if the castings do not interlock readily, they will strike insuch a manner on the slanting side of the teeth that a little additionalpressure will. crowd them closely turns the rosette R, thereby turningthe rod.

M, upon which rests strip K, until the eccentric O interlocks thecastings I J by crowding strip K upward.

I have discovered that when eccentric O is thrown downward strip K doesnot alwgys drop readily, and so, to obviate the difficulty, I place onstrip K the rigid pin to, and on rod M the rigid pin 3 When rod M isturned so as to throw the eccentric O downward, the rigid pin y strikesupon pin w and forces the castings apart.

It will readily be seen that, in the manner described, the seat issecurely locked and easily unlocked by the occupant or attendant turningthe rosette R about one quarter around, which improvements, inconnection with the hinged back and coiled spring, I believe make thisthe most desirable adjustable recliningchair known.

I am aware that a single ratchet or cog track has been used, with a pawlor pin to hold the seat-frame in a given position, and therefore I donot claim the use of the notched or sawtoothed casting broadly; but

What I claim, and desire to secure by Letters Patent, is

In combination, sliding seat D, provided with the casting I on strip H,hinged strip K, provided with the counterpart casting J and rigid pinWV, and eccentric-rod M, provided with the rigid pin y and rigidlyfastened to rosette R, all. arranged and operated as set forth, and forthe purposes specified.
